According to the early teachings of St. Cyril, who lived in the 4th Century and is a Doctor of the Church, Communion in the Ancient Church was indeed received in the hands.
“Approaching, do not come with thy palms stretched flat nor with fingers separated. But making thy left hand a seat for thy right, and hollowing thy palm, receive the Body of Christ, responding Amen. And having with care hallowed thine eyes by the touch of the Holy Body, take it, vigilant lest thou drop any of it. For shouldst thou lose any of it, it is as though thou wast deprived of a member of thy own body.” “Then after Communion of the Body of Christ, approach the Chalice of His Blood, not extending thy hands, but bending low, and with adoration and reverence saying Amen, sanctify thyself by receiving also the Blood of Christ. And while thy lips are yet wet, touch them with thy hands, and sanctify thy eyes and thy forehead and thy other senses” (Cat. Myst., v, 22, 21-22).

The wafer form of the host with which most of us are familiar is a later development in Christianity, as well, as the number of Christians increased.
A pious act of a young priest that I knew was to bake the bread that was to used at the Masses he celebrated.
Whether a person receives Communion on the hand or tongue, what is most important is that he receive with reverence and awe.
